Definitions

  • the present invention concerns an alpine ski with an upturned tip, a main section with concave curved sides and an essentially flat sliding surface.
  • the object of the invention is classified in Class A 63C 5/00 Int . Cl 4.
  • alpine ski comprising aforementioned features is known from the PCT patent application WO 92/00020 (J ⁇ rgen KARLSEN, Norway). Said known alpine ski is based on the principle that a front and a rear section, respectively, are considerably wider than the main section thereof.
  • the front section at least 20 cm lengthwise of the main section has sides the lower edges of which diverge so markedly upwards and outwards to the sides in relation to the imagined straight parallel lines constituting extensions of the lower edges of the sides of the rest of the main section that at the transition between the main section and the tip, the ski has a width of 15-70%, preferably 15-50% and, best of all, a width of 20-30% greater than the width at the transition between the front section and the rest of the main section.
  • the lower edge of each side diverges upwards and is thereby sufficiently raised from snow to prevent cutting into the snow when the ski is positioned on its edge despite the increased ski width at the front and the rear end, respectively.
  • an alpine ski of the general kind discussed in the foregoing by which, however, the construction is further improved in a manner that the active length thereof is irrespectively of the manner and kind of skiing, i.e. nonprofessional or professional and slalom or downhill skiing, respectively, utilized to the optimum and which enables performing of a turn on the edge of the ski with least skidding possible.
  • Said smooth curve having a continuous derivative of the second order could be a part of an envelope of each circle of the curvature of the given curve which is at a given moment during steering through the turn performed by a skier, a part of an arc of a circle, brachistochrone, cycloid or a part of any combination of sine curves.
  • Another essential feature of the alpine ski according to the invention lies in that a uniformly increasing width thereof reaches maximum values in an extremely wide front section, i.e. in the area of the tip, and in an extremely wide rear section, i.e. in the area of the tail.
  • the relation between the narrow middle section and the widest front section lies in a ratio of 1: 1.47 to 1: 2.07, preferably 1: 1.75
  • the relation between the narrow middle section and the widest rear section lies in a ratio of 1: 1.32 to 1: 1.90, preferably 1: 1.59.
  • An alpine ski according to the invention comprises a narrow middle section 1 being essentially located in the area of the standing room of the skier.
  • the width of said ski uniformly increases in longitudinal direction, i.e. in the direction towards tip 2 as well as in the direction towards tail 3, reaching its maxima in an extremely wide front section A-A lying in the area of the upturned tip 1, i.e. section averted from snow, and in an extremely wide rear section B-B lying in the area of tail 3 of the ski.
  • the ski further comprises concave sides 4, 4'.
  • said sides 4, 4' of the ski according to the invention are formed in such manner that each single point of each side 4 and 4', respectively, is arranged on a smooth, uniform curve whose essential feature is that it has a continuous derivative of the second order.
  • a part of an arc of a circle, brachistochrone, cycloid or a part of any combination of sine curves could be chosen as said smooth curve having a continuous derivative of the second order.
  • Said curve of the sides 4, 4' could also be a part of an envelope of each circle of the curvature of the given curve which is performed by a skier at a given moment during steering through a turn.
  • the ratio of the narrow middle section 1 and the widest front section A-A lay within a range of 1: 1.47 to 1: 2.07, preferably 1: 1.75.
  • the ratio of the narrow middle section 1 and the widest rear section B-B lies within range of 1: 1.32 to 1: 1.90, preferably 1: 1.59.
  • a specific embodiment of an alpine ski has been conceived in such manner that the width thereof at its narrowest point, i.e. in the middle section 1, lies within the range of 63 ⁇ 5 mm , at its widest front section A-A the width thereof lies within range of 110 ⁇ 10 mm and at its widest rear section B-B the width thereof lies within range of 100 ⁇ 10 m .
